Three of them struggled with 29-year-old Tavares Docher until a paramedic gave him a sedative to subdue him.

Docher has since been in a coma, and his family wants answers. The St. Lucie County Sheriff's Office isn't commenting on the pending investigation, although its insurance company sent a bill to Docher's family requesting payment for medical expenses incurred by one of the deputies involved in the confrontation.

The Dochers haven't gotten many answers, but the request for medical records indicates the State Attorney's Office is opening an investigation.

Such an investigation likely would yield answers to questions about what sedative was administered and how often the procedure is used.
